BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 625,866, dated May 36,1899.

Application filed October 9, 1897.

To all whom it mag concern.- 7

Be it known that we, THEOPHILE EDOUARD AYoT'rE and ARTHUR ALBERTCHAEBON- NEAU, of Montreal, in the Province of Quebec and Dominion ofCanada, have invented a new and Improved Brick-Machine, of which thefollowing is a full, clear, and exact description.

This invention relates to machines for the manufacture of brick,artificial stone, and ornamental brick; and the object is to provide amachine of this character that may be operated with dry or semidry clayand with which a comparatively large number of brick may be formed withthe help of one or two operators. I

We will describe a brick-machine embody ing our invention and then pointout the novel features in the appended claims.

Reference is to be had to the accompanying. drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding-parts in all the views. j

Figure 1 is a side elevation of a brick-machine embodying our invention.Fig. 2 is an end view thereof. Fig. 3 is a section on the line 3 3 ofFig. 1. Fig. 4 isa section on the line 4 4 of Fig. 2. Fig. 5 is a planview of a mold employed.- Fig. 6 is an edge View thereof.

Fig. 7 is a plan view of a carrier-rack em-,, ployed. Fig. 8 is a planview of a clay-cut ter employed, and Fig. 9 is a detail showing aplunger-operating mechanism.

This machine is double-acting-that is, it, is provided with two sets ofpressing devices operating alternately and in conj unction'with j areciprocating mold.

Referring to the drawings, 1 designates a frame, which must bestronglyconstructed, so that it will resist the vibration caused byMounted to move vertically in suitable guideways at the. ends of theframe 1 are the upper plungers 2 and 3 and the coacting lower plungers 4and 5. The upper plungers 2 and3 are operated, respectively, by levers 6and 7, which are fulcrumed at oneend to the machine-frame and have links8 and 9, extended to the plungers.

The levers 6 and 7 are horizontally disposed,

and from the outer end of the levers 6 arms Serial No. 654,662. (Nomodel.)

similar to the arms 10 and engaging with cams at the opposite end of themachine similarly to the cam-disks 11. The cams for the arms 10 and 13are operated by a longitudinally-disposed shaft 14, having bevel-gears15, engaging with bevel-gears 24 on the shafts 6o 12. One shaft 12 has agear-wheel 17 secured to it, and this bevel-gear 17 engages with ,apinion 18 on the shaft of a gear-wheel 19, meshing with a pinion 20,secured to the shaft of a driving-pulley 21, from which power may betransmitted by any suitable motor;

The lower plungers 4 and 5 have link connections with levers 22 and 23.The outer ends of the levers 22 engage in grooves in cam-disks 24*,mounted on the shaft 12, and

the levers 23 engage with similar cams on the shaft operated by theshaft 14. The several plungers have head portions each of a surface areaequal to that of a brick or similar article to be manufactured,"andthere may be any desired number of these heads on the plunge-rs,equaling, of course, the number of openings in the mold.

The mold, as shown in Fig. 5, comprises a frame 25, having two sets ofmold-cavities 26, So

one set designed to be operated in connection with the plungers 2 and 4and the other set in connection with the plungers3 and 5. The

moldboard or frame 25 is movable longitudinally of the frame 1. providedat its opposite sides with tongues engaging in slideways in the sides ofthe .frame.

Reciprocating motion is imparted to the moldboard or frame 25 by meansof levers 27, fulcrumed on the frame 1 and having link 0 connections 28with pins extended from the tongue portions of the moldboard throughlongitudinal slots in the frame. The lower ends of the levers 27 areconnected to rods 29, having pins 30 extended into cam-groo'ves-3l 95 ofcam-disks 32, mounted on a shaft driven by means of a gear-wheel 33,mounted on said shaft and engaging with a pinion 34 on the shaftoperating the arms 13; It may be here stated that the arms 10 and13 areheld sub- I00 As here shown, it is stantially in vertical alinement bymeans of pins 35, extended into slots formed vertically in the sideframes 1.

Mounted in the frame 1, between the sets of plungers, is a clay mixingand flushing oasing 36, which may be divided by means of av centralpartition into two chambers, and in each chamber a shaft 37 is mountedto rotate.

On the shaft 37 are outwardly-extending fingers 38, and at the lowerendsof the shafts bevel-gears 40, engaging with bevelgears 41 j on a shaft42, mounted in bearings on the top of the casing 36, and the outer endof this shaft 42 is provided with a sprocketwheel 43, from which asprocket-chain 44 extends to a connection with a sprocket-Wheel 45 onthe shaft of the driving-pulley 21.

In the lower portion of the casing 36 is a grating 46, having a numberof openings equal to the number of openings in each section ofthe'moldboard and designed to register at a certain time with theopenings in the moldboard. This grating 46 consists of upper and lowersections, and between the upper and lower sections a clay-cutting deviceis movable. This clay-cutting device consists of a frame 47, designed tobe reciprocated across the grating and having a number of cuttingwires48. Reciprocating motion is imparted to "the cutting device by means ofa cam 49, mounted on the shaft 14 and in the camgroove of which a rolleron an angle-lever 50 engages. The vertically-disposed member of theangle-lever 50 is fulcrumed to a bracket 51, extended outward from theframe, and the upper end of this vertically-disposed portion of thelever is pivoted to lugs 52, extended from the frame 47. The oppositeend of the frame'47 has pivotal connection with a link 53, the lower endof which is pivoted to a;

bracket 54, extended from the frame 1.

Secured within the frame 1, below the reciprocating moldboard 25, is atable 55, having a series of openings at each-end designed to registerwith openings through the moldboard. At the central portion this tablewill form a bottom for the mold-openings when the clay is pressedtherein by means of the spiral blades 39.

Movable at the sides of each plunger-4 and? 5 are carrier-chains 56.These carrier-chains I are reciprocated transversely of themachineframe, and, as here shown,-the chains are extended around rollers57, mounted on the corners of laterally-disposed frames 58. Re-.ci'procating motion is imparted to the chains:

56 by means of sprocket-chains 59, engaging with sprocket-wheels onshafts of the chain-.-

driving wheels and engaging with sprocketwheels 60, on the shaft 61 ofwhich are mounted pinions 62, engaged by segment-racks 63,

pivoted to the machine-frame,and from which rods 64 extend to engagementwith camwheels 65 on the shaft 14.

In operation the clayor other material to be formed will be placed inthe receptacle 36, where it will be pulverized by the fingers 38 andforced through the grating 46 into the mold-openings at one end of themoldboard. Then the cutting device will be reciprocated to sever theclay in the molds from that in the receptacle 36, after which themoldboard will be moved to bring its filled molds underneath one of theupper plungers, here shown as the plunger 2. When in this position, theupper and lower plungers 2 and 4 will be moved to press the material inthe mold-openings. Then the lower plunger 4 will be moved downward tobring its plunger-heads below or substantially on the plane of the upperstretches of the chains 56, and then a carrier or receiving-rack 66 isto be placed on the chains below the moldboard. The upper plunger 2 willthen move downward, so that the plunger heads thereof will force theformed brick out of the mold onto the carrier or rack 66. Then thechains 56 will be operated to move said carrier or rack outward to theside of the machine, where it is to be received by a transporting devicehereinafter to be described. While this operation is taking place, claywill of course be fed into the openings inthe opposite end of themoldboard, to be moved between the plungers 3 and 5 and operated in themanner as before described.

It may be here stated that to prevent the sticking of clay to theplungers the said plungers and plunger-heads should be suitably heated.They 'may'therefore be made hollow in the usual manner and supplied withsteam.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. A brick-press,comprising two pairs of upperand lower plungers, a moldboard, means for moving the mold-board to thepairs of plungers alternately, a feeder for feeding clay into saidmoldboard, a cutter operating between the feeder and moldboard,and meansfor moving the moldboard to and from the pressing-plungers,substantially as specified.
